VW Concept Microcar Gets 235 MPG 507
Hugh Pickens writes "Volkswagen is bringing new meaning to the term 'fuel efficiency' with a bullet-shaped microcar that gets 235 mpg. Called the One-Liter, because that's how much fuel it needs to go 100 kilometers, the body's made of carbon fiber to minimize weight and the One-Liter makes extensive use of magnesium, titanium and aluminum so the entire vehicle weighs in at 660 pounds. Aerodynamics plays a big role in its fuel economy, so the car is long and low, coming in at 11.4 feet long, 4.1 feet wide and 3.3 feet tall with a coefficient of drag of 0.16, a little more than half that of an average car. The One-Liter could have a sticker price of anywhere from $31,750 to $47,622, and VW plans to build a limited number in 2010."

Of course, statistics can be misleading. In this case, the vehicle actually got 285mpg in a test run. However, thus run was at 45mph rather than a more typical 55mph; there's 1 1/2 times the aerodynamic drag at 55mph. Rolling losses will be higher by 1.2x. Let's say an overall 1.4x higher, since aerodynamic drag dominates at higher speeds; converting, we get 203mpg. Next, this wasn't a normal drive cycle, but a person trying to optimize their ride. Let's be generous and only cut it to 180mpg. It's a diesel, and diesel is about 15% more dense than gasoline, and emits about 15% more CO2; cut it to 155mpg for a gasoline-equivalent. The production version is going from a 1 cylinder to a 2 cylinder mild hybrid, since the 1 cylinder has poor acceleration. This won't hit it as much as normal, since the car operates on an acceleration/coasting system of maintaining sped, but it should at least hit it a little; let's say 145mpg. The production version is also going to be getting heavier, since this version omitted all of the standard things like airbags and so on. Let's say 130mpg to be generous. And if they widen it to make it more stable (it's quite narrow), it'll get more aerodynamic drag and go lower still. Same if they try and reinforce that frame and skin -- carbon fiber is great, but they're not using much of it, and magnesium (which makes up the bulk of the frame) is even weaker than aluminum. And if they try to make it more affordable by, say, swapping the carbon fiber and magnesium for aluminum and kevlar or fiberglass or whatnot (it's current projected *subsidized* price is, if I recall correctly, something like $40-60k USD), that'll drop further still. Also, since it only has a rather limited regen capability, its city mileage will be lower than its highway mileage.
Now, even with all of this, it's still one darned efficient vehicle. It's just not as impressive as the original claims. It's easy to manipulate numbers to try and make a vehicle look more efficient than it is. For example, with the Aptera. You generally see two numbers for it: 230mpg and 300mpg. Both are bogus. 230mpg was what the Mk0 got at 55mph. However, it too was a shell, and was not as safe or full of the things needed to meet legal requirements as the Mk1. It was also a diesel. Converting to the Mk1 pre-production model, its charge sustaining mileage went all the way down to 130mpg. However, they generally cite 300mpg, under the excuse that most people don't go on long trips very often, so it'll usually run just on electricity, which they don't count. It's still misleading; many people I've talked to thought you could go cross-country on 300mpg. Nope, not without charging every hundred miles or so. Mind you, Aptera is hardly alone in doing this; virtually all of the PHEV makers do it, and some are a lot worse offenders than others. I remember seeing an article about an SUV that got "150mpg". If you look at how they did their numbers, they were assuming that only something like 1/7th of its miles ran on gasoline, and only counting the gasoline.
In short: before you believe inflated mileage claims, look into the numbers.
On the subject of Aptera vs. 1L car: it's interesting the approaches taken by Aptera and the 1L car. The 1L car doesn't take streamlining as far. They move the rear wheels close together, but not so far as to make it a three wheeler. They lift the rear a little off the ground to eliminate ground turbulence, but not nearly as much as the Aptera -- nor do they use cabin air to fill in their wake. Overall, their drag coeff is 0.19, compared to 0.11 for the Aptera. However, while Aptera decided to make one significant compromise on efficiency -- requiring side-by-side seating to make it more acceptable to the general public -- Volkswagen did not. Their tandem seating arrangement reduces frontal area. While there are some downsides to tandem seating, it would be interesting to see a vehicle that takes a combined approach, with the extreme streamlining of an Aptera, along with its hig

As long as it has crumple zones (remember---what you really care about is the acceleration of your own body (which gives the force on you), and that's inversely proportional to the distance you have to travel, given an initial and final velocity), I don't see how it's any less safer than a bulkier car with identical length of crumple zone.

There really wasn't any need for a 1.6 L engine in the GX3. They could have gone with the engine from the Lupo 3L, which was a 1.2 L inline three cylinder TDI engine that made 61 bhp.
Of course, the first thing they should do is bring the Lupo 3L back to life and bring it to the US.
The Lupo 3L weighed about 1830 lb, and the GX3 weighed about about 1260 lb, so you can see that the Lupo 3L engine would still give quite interesting performance in the GX3 chassis, and the fuel consumption, with a new aerodynamic, enclosed chassis for the GX3 should enable that configuration to easily reach at least the ~80 mpg of the Lupo 3L, and probably even better that figure by a good margin, while offering the advantages of side-by-side seating.

Not to mention the Honda Civic can haul you, your family and your stuff at that price, this VW? Nope.
We won't even get into the cost of money and the lost value of paying the high up-front charges of the VW option.
Re:How much does it cost??!! (Score:5, Informative)
That's where the fallacy lies - do the math.
How about we actually put pen to paper on this one and figure out exactly how much money we would save in fuel costs each year :
I am going to be generous and work with easy numbers - $4 gasoline, 1,200 miles per month.
Start with a relatively easy to find 40 mpg car :
1,200 miles / 40mpg = 30 gallons * $4 = $120 per month.
Crank that up to one of those Volkswagon TDI or a hybrid getting 50 mpg :
1,200 miles / 50mpg = 24 gallons * $4 = $96 per month. Saved about $25 per month.
And now for this ultra-cool one man car made of recycled SR-71 parts at 235 mpg :
1,200 miles / 235mpg = 5 gallons!
5 * $4 = $20 total fuel costs for the month. Which sounds great, except it's only saving about $75 per month, assuming the production models get the same mileage as their hand made prototype - which isn't going to happen.
Let's pretend they get them in viable quantities getting 120mpg, which is still crazy good, right?
1,200 miles / 120mpg = still only 10 gallons, which is only $40. Pretty awesome!
Except compared to a current Prius or a VW TDI, you're only saving $55 a month.
It's because of the way the 1/x curve flattens out on the tail end, after about 40-50 mpg it really doesn't make much of a difference. The dollar difference between 40mpg and 120mpg is the same dollar difference between 17mpg and 21mpg, again - because the curve of 1/x is so high below 20mpg. Get down into the 9mpg-11mpg range and difference for every 1mpg = $40.
Want to make a killer difference in our gas consumption, engineer a way to make the current 500 million cars already on the roads today get 3 more mpg, because I figure 1/3rd of the cars on the road are in the sub 20mpg range.
I already figured that one out too - tire pressure during the winter. I used to think that the gas stations used different formulas in the winter (which they probably do) which is why my gas mileage went from 21 in the summer to 17 in the winter (which wasn't why.) My most recent car has air pressure sensors on the tires so I noticed that during the winter months the air pressure in the tires dropped from 35psi to about 28psi (cold air shrinks) - when I pressured up my tires to the suggested 35psi, my gas mileage went right back to 21mpg. How many people go the entire winter without adding air to their tires (well ... it doesn't look flat and it had plenty of air in August, air isn't leaking out ...) and spend their entire lives thinking the reason they get crap gas mileage in the winter because of the 'winter gasoline formula'? Bingo.

I drive a pickup, which is about as bad as it gets in terms of gas mileage. It's a 2002 model, and it has about 68,000 miles on it, which translates to about 4,000 gallons of fuel that it's used thus far. At $4.00/gallon (far above the average cost of gas over the period I've owned it), that's $16,000. I paid about $19,000 for the truck after all was said and done, so even if this new car had *no fuel cost at all*, it still wouldn't break even until after it had been

A "Manhattan Project" (Score:5, Interesting)
I totally agree.
Neal Boortz, a local talk show host that tends to sway conservative where I live, keeps railing on how the U.S. needs to have a "Manhattan Project" to explore for oil and develop domestic resources. He says that within three years, if we really focus our time, effort, energy, money, and our brightest minds on it, we could wean ourselves off dependence on foreign oil by replacing it with oil from domestic sources.
I can't help but think, if we're going to gather our time, effort, energy, money, and brightest minds, why can't we come up with a "Manhattan Project" to wean ourselves off of oil entirely?
I'm so tired of the U.S. taking a technological back seat to the rest of the world, but it looks like we're about to yet again. Let other countries develop, test, and build the products while we sit back and get further behind. That way, we'll have yet more industries we can't compete with and yet a higher trade deficit.

Yep you nailed it. The gas prices we're seeing have less to do with scarcity, and more to do with a captive market - well, that and the fact that the majority of oil producing countries are literally overrun by the OPEC cartels, which is what inevitably happens when you stick a trillion-dollar business in a 3rd world country.
I agree, we don't need fuel efficiency, we need a whole new form of fuel. One that doesn't shackle every civilized nation to every uncivilized oil producer.
